Isidore of Seville and Adoption

St. Isidore, by Murillo



Religious Leader/Historian

St. Isidore of Seville was from a noble family of Cartagena, but was orphaned as a child and educated by his elder brother, St. Leander, in a monastery. (Another brother and sister are also saints.)

He became archbishop of Seville in about 600, succeeding his brother. He was famous for his learning, holiness, generosity and organizational ability. He presided over the Council of Toledo and 633 and other major Spanish councils of the Church.

He wrote many important books which influenced later writers, and remarkably for his period, all his known writings have survived, including the Etymologiae, an encyclopedic compilation of contemporary knowledge in many fields.

His feast day is 4 April. In 2001 he was declared patron saint of the Internet by the Catholic Church.
